If you own an NPC and also use the new silver PSA remote (the backlit one), you should be aware of the following.
When the NPC was new, we were told to leave it on all the time for best SQ. The blue PS logo is not a standby button as it is on other pieces. Touching any of the front buttons turned on the display if adjustments were needed.
After getting my BHK pre, I started using the silver remote to put the pre, the DS DAC, and (later) the DMP into standby by hitting the ‘Off’ button. This also affects the NPC; the display (if on) and the blue logo go off. (The NPC manual makes no mention of the fact that it even has an IR sensor.) Once put in standby this way, touching one of the buttons on the NPC turns on the blue logo – so you think the unit is back on – but unless you turn it on with the remote, the display refuses to come to life. In my system the NPC sits to one side of the stack with the pre, the DS, and the DMP, so it doesn’t always get affected when I turn the other pieces on with the remote. I was used to just touching a button on the NPC, but this now does not work unless the NPC has been woken up with the remote. Took me a while to figure this out.
I also learned that the four Phono Preamp buttons on the remote do work with the NPC to adjust input (phono/analog), phase, and mono/stereo. Very convenient, although unexpected since the NPC has been discontinued .
